Fertilize under the drain should be throughout the season. However, many gardeners believe that after harvesting, the work on top-uping this stone fruit is completed. But this is not so.
After harvesting, be sure to feed the plum before the impending cold. In addition, this tree has just finished bearing fruit, and most of the nutrients the tree has spent on flowering and ripening. Therefore, the tree is weakened, and before the onset of cold weather, it should be fed so that the plum normally tolerates the winter and does not freeze.
How, when and how to fertilize plum trees in the autumn, and will be described below.
Plum trees grow well and bear fruit on soils with a pH of more than 6.0. If the soil on the plot is more acidic, then ash (dry or solution with this organic fertilizer) is added to the trunk circle under these stone fruit trees or watered with a solution of hydrated lime. When the fruits begin to ripen actively (from the first to the last ten days of August), then a mixture containing ammonia fertilizers should be added to the plum to improve their quality.
To maintain the strength of this fruit plant before the cold, you can use one of the following nutritional supplements:
Such fertilizers are applied in September - early October, while the weather is relatively warm, in this case, nutrients will have time to reach the roots and be absorbed by the tree in full. As soon as the cooling starts. All types of top dressing stop.
You should not exceed the norms of fertilizers introduced during this period, because the plum can freeze in the winter, and fertilizers will simply be wasted.
Seedlings that were planted in open ground only in spring should not be fed more than once during the fall. You can apply any of the above fertilizers, but in the form of a solution (you should dilute the prescribed dose in a bucket of water).
Trees that already grow on a plot of at least three seasons can be fed in the fall with all kinds of fertilizers (except for urea and other nitrogen-containing mineral fertilizers). Feeding should be done no more than 1 time in 7 days. After the last dose of fertilizer has been applied, the trunk circle should be mulched with old foliage or dry grass.
Determine what fertilizer should be applied under the drain, it is visible by the state of the tree itself. Particular attention should be paid to the growth of shoots, how healthy the tree is, and how many fruits are harvested from plums.
